WeWalk Smart Cane 2 With TDK New Sensors

At CES this January, I had the opportunity to explore the latest technologies. One standout innovation was the WeWalk Smart Cane 2 at the TDK booth. This next-generation assistive device is designed for blind and visually impaired users and offers groundbreaking features that set it apart from traditional white canes.

The WeWalk Smart Cane 2 has advanced sensors, making it the most sophisticated white cane I’ve encountered. Its standout feature is a vertical radar for obstacle detection, which identifies objects that conventional canes might miss, such as overhead branches that could strike the user’s face.

The vertical radar beam ensures comprehensive detection. When an obstacle is detected, the cane alerts the user through vibrations or audio cues reminiscent of proximity sensors in modern vehicles.

Building on the original model, this version incorporates improved sensors and AI capabilities, showcasing how artificial intelligence can take assistive technologies to the next level.

When paired with a smartphone, the cane’s motion sensors deliver precise navigation and context-aware information about nearby stores and buildings. This functionality is particularly valuable for users who rely on non-visual cues. While I haven’t tested it outdoors, it seems likely that the data is sourced from mapping applications, providing details such as street names, store information, and even menu options.

Its voice interaction capability makes the WeWalk Smart Cane 2 even more user-friendly. Users can keep their smartphones tucked away, as the cane has a microphone and speaker, effectively transforming it into an intelligent assistant. This feature streamlines interactions, making it easier for users to navigate their environment hands-free. The device boasts a battery life of approximately 20 hours, avoiding battery anxiety.

The cane’s handle houses all the intelligent features. The lower portion of it retains the standard design of a foldable white cane, ensuring familiarity for users. This thoughtful integration of technology and traditional design enhances its appeal and usability.

The potential impact of the WeWalk Smart Cane 2 on the lives of visually impaired individuals is significant. Priced at approximately $800 with a $5 monthly subscription, it is notably more expensive than traditional canes. However, the advanced functionality it offers—especially the vertical radar—justifies the cost for those who can afford it. This device represents a meaningful leap forward in assistive technology, bridging the gap between essential mobility tools and intelligent systems.

During the demonstration, I saw a black version of the cane, though a white version is also available. This innovation underscores how technology can transform lives, and the WeWalk Smart Cane 2 is a prime example of how thoughtful design can address real-world challenges for those with visual impairments.

To make this technological feat happen, the WeWALK Smart Cane 2 includes the following TDK hardware:

InvenSense SmartMotion (ICM ICM-456xy): 6-axis IMU sensor, for indoor and outdoor environments with an integrated gyroscope and accelerometer (motion sensor). TDK is constantly working on making this smaller, and lower-power.
InvenSense SmartSound: low-power microphone that enables an intelligent voice assistant
InvenSense SmartSonic (ICU-20201): Ultrasonic time-of-flight sensor, for presence detection and obstacle avoidance at a distance up to ~9.5 yards (31 feet), which is way beyond what conventional canes can do.
